Motivation

I have noticed that many users end their posts or comments with a unique phrase, avatar, picture that make their post "stand out", much as @amiramnoam suggested in his post about how to make yourself stand out on Steem.
These post footers are manually added repetetively to any post.

Solution

Adding a Signature feature to Steemit, Busy.org etc. That allows users to pre-set their custom post feature in their profile by adding a textarea like this:

The length of the signature should not exceed a certain limit in order to prevent spam and consume as little bandwith as possible
Possible limitation should be max. of 100 charactes in 3 rows (or one picture not exceeding 4rem, which is about four rows)

This is how it would look when starting to write a new post, the signature is added in the end (so the user can decide to remove or change it for this certain post):

Thoughts

Do you think this will be a time saver? Do you have any ideas to improve the suggestion? I'd be glad to hear from you! (And implementing this feature, also)
